Surmounting the plate '11 and pivoted on a bolt12 is a head 13 having a drop-pawl 14' which is adapted to engage any of the teeth of the plate 11 to lock thejframe 10 and the disks 8 in any position to which they may be pivot bolt 12. p V

The head 13 and the cross-head 3 are adjustably looked together by a rose or ratchet clutch 15.. whose sections are carried by said parts. f i Carried by the cross head 8 is a pivot 16 which passes through a hole in the clutch 15 and carries a cam locking lever 17, pivoted thereto at 18. On depressing the lever 17, the sections of the clutch areengaged and on raising said lever, they are disengaged. The coupling or clutch thus provided enables the gangs of disks 9 tov be tilted with their axes of rotation at any desired inclination and to be held in their adjusted positions.

It will be observed'that the yoke 10 can be swung to any desired position and evencompletely reversed without removing a single bolt or fastening and thus the dirt can be thrown to. and from he row as ma be desired.

The cross heads 2 may have an additional hole or holder 7 to accommodate an .extra shovel shank to'each cross head when shovels, instead of disks, are used.

lVhat I claim is: V

1. A. disk cultivator attachment for cultivators, comprising disks, a cross head to which they are connected, and similar, in dependent, reversible attaching arms or members reversibly. connected to said cross head, by which theattachment may be connected to acult-ivator. V v

2. A disk cultivator attachment for cultivators, comprising disks, a cross headto which they are connected, and similar, independent, reversible angle-shape arms ,or members reversibly connected to the cross head and constituting means by which the attachment may be connected to a cultivator.

3. A disk cultivator attachment for cultivators, comprising disks, a cross head to which they areconnected, and duplicate, detachable and interchangablereversible angle-shape arms or members reversibly connected to the cross head, by which the attachment may be connected to a cultivator.

i. A disk cultivator attachment for cultivators, comprising disks, a cross head to which they are connected, said cross head having a plurality of seats, arms or members adapted. to be engagedwith different bers or. arms adapted for interchange with each other and for reversing as also for positioning inany at said seats, and means ior securing the said angle-shape members in said seatsf'said -members constituting means whereby the attachment may be secured toa cultivator. V

6. Ina disk cultivator attachment for cultivators, the combination withthe cultivator frame anda cross-head mounted thereon, of

a diskgangcarrying cross-head, a clutch head pivoted to said disk-gang-carrying cross-head for turning on a general horizontal axis, a cam leverfor engaging and disengaging; said clutch head with the diskcarrying cross head, a yoke pivotally; suspended from said clutch head on a general vertical axis, disks carried by said yoke, teeth carried by the yoke, and a locking pawl carried by the clutch and engageable with the said teeth. 7 1

7. A unitary" disk" cultivator attachment for cultivators comprising the combination withthe cultivator frame and a cross-head mounted thereon, of a disk-gang-carrying cross-head, reversible arms or members carried by said disk-gang-carrying cross-head for connecting said cross head to the cross head of a cultivator, a yoke, disks carried by said yoke, a clutch headpivotally carried by the disk-gang-carrying cross head and pivotallycarrying the yoke whereby the disks are .mounted for horizontal swinging and for tilting, and independent locking means for securing the head and disk-gang-carrying cross head together and the head and yoke together, respectively. v

In testimony whereof I afliX my signature.
